不可以
两句话的意思不同
he was in the R.A.F 指他原来在R.A.F ，现在已经不在了
而用has been的现在完成时，表示他至今仍然在那儿

不可以，
He was in the R.A.F 表示他之前是在R.A.F，但不知道有多久，去旅游还是定居。
He has been in the R.A.F. 表示他之前是在R.A.F很长时间。
这是我的感觉拉！

不可以。
He was in the R.A.F 强调的是在某个过去的时间点他曾经待在R.A.F，后面可以加个具体的时间点来强调。

He has been in the R.A.F强调的是他一直在 R.A.F，但并没有强调具体的时间。

He was in the R.A.F 可以改成He has been in the R.A.F吗 he was ageneral in the army he was walking in the forest when he was bitten on the leg by a sanke 7 ___ (cathch)in the rain, he was wet .... the manager told me that he was born in 1976 13.
